I have used Rosa and Ramon with R&R Mechanical Services for many projects. They are fantastic. The most recent project they did for my business was to replace a water heater. It is working perfectly. I am always treated nicely when I call to request service and Ramon is courteous and professional when he comes to do a repair. I highly recommend them. They are very dependable and on time. I plan to call them anytime I need service or repair on our plumbing or HVAC system.
